Arjuna asteroid
The Arjuna asteroids are a class of near-Earth asteroids whose orbits are very Earth-like in character, having low inclination, orbital periods close to one Earth year, and low eccentricity. Arjunas are very uncommon, but of significance owing to the extremely low delta V required to reach them from Earth.
The Arjuna definition is somewhat fuzzy and covers the definition of the tree well-established families Apollo, Amor and Aten.
